Description

Sufficient device of changing dressings of diabetes

Technical Field

The utility model relates to the technical field of medical equipment, specifically a sufficient device of changing dressings of diabetes.

Background

Worldwide diabetic patients were 4.25 billion in 2017, and this figure is expected to grow to 6.29 billion by 2045, with 75% of patients from low-to-medium income countries. Diabetic foot disease, as far-end nerve abnormality of lower limbs and far-end peripheral vascular lesion of lower limbs caused by diabetes, not only brings great strain to patients, but also brings heavy economic burden to society and families. Whereas foot ulcers are easily associated with infection as a critical clinical situation, only 2/3 diabetic foot ulcers eventually heal, with up to 28% of foot ulcer patients eventually leading to lower limb amputations of varying degrees. The number of amputations to varying degrees due to diabetic foot is over 100 million each year, i.e., about every 20s of the world, a patient loses their lower limb due to diabetes.

Therefore, the early diagnosis and the standard dressing change of the foot ulcer and the infection thereof can not only improve the curative effect and promote the healing of the ulcer, but also be an effective way for ensuring the basic measures of amputation and saving the medical cost.

However, although the wound surface of some diabetic feet is small, the wounds are deep, and even if the diabetic feet are completely debrided, the problems of more seepage liquid, inconvenient flushing, unsmooth drainage and the like still exist in the subsequent dressing change process. There are currently two methods of treatment clinically for this type of wound: one is gauze filling drainage, namely sterile gauze soaked with a disinfection product is sent into a wound through a pair of sterile scissors or tweezers to achieve the effects of simple drainage, cleaning and disinfection, but the depth of the sterile gauze which can contact the wound is limited by the pair of tweezers and the sterile scissors, the sterile gauze cannot be fully sent into the wound with a long sinus, part of blind ends of the wound cannot be fully treated, the drainage and filling effects which can be achieved by the gauze are common, frequent dressing change is needed, and the pain of a patient is increased; the second is vsd drainage, and although there is vsd drainage device application comparatively ripe now, it has the expense higher, and the wound bed is difficult to prolong drawback such as skin after the drainage.
